The group identified the password Zuckerberg used as “dadada.”

Facebook Inc. released a statement Monday morning saying that none of the company’s systems or accounts were accessed and that Zuckerberg’s affected accounts have since been re-secured.

The group also hacked into his Pinterest account which has since been restored.

The OurMine Team claimed it gained access to the password from passwords leaked in a massive LinkedIn data breach in May.
